Hi from Paris,
First problem :
I have a .gif file that I display in an image, using a
button script (see below). The file displays correctly,
but it is reduced in size to fit my stack window (which,
in fact, is exactly what I wanted). However, it is too
small to see the fine print (it is a Census file). I would
sometimes like to zoom on it, and use a "hand" (as for
PDF files) to explore the image, but within my image
dimensions. Can this be done ?
Second problem :
My image has a "hide me" script which clears the
window, so I can display other .gif files. If I then
click on the same display button, my .gif file is
now displayed in full size (but obviously only a
part of it). Why is this ?
Any help gratefully appreciated.
global GVC1FileName -- Valid file name
hide image "MyImage"
set the filename of image "MyImage" to GVC1FileName
-- put the formattedheight of image "MyImage" into GVHeight
-- put the formattedwidth of image "MyImage" into GVWidth
set the rect of image "MyImage" to 79,16,733,574 -- Window limits.
show image "MyImage"
